摘要: Abstract The formability of aluminum alloy AA7075 at elevated temperature was investigated through experiment. Stress–strain relationship different temperatures and forming speeds were tensile testing. Deep drawing stretch also tested limiting ratio (LDR) dome height (LDH) tests. Finally, post mechanical property testing conducted to investigate the effects exposure warm on properties. Results show that deep can be significantly improved when blank is heated 140–220°C. At over 260°C, properties begin decrease due effect heating processes material's temper.
